A mudslide 4 miles long, 2 miles wide, and about 250 feet deep struck in western Colorado's Mesa County Sunday evening. The area is rural, so no structural damage has been reported, though at least three residents are missing.
The mudslide, described as sounding like a freight train, was reported at about 6:15 p.m. Rescue teams raced to the scene, but were forced to ease operations by nightfall as the slide area was unstable. The avalanche comes just two months after a Washington state mudslide, which was 1-square mile in size, killed 43 people.
